The usefulness of personal ventilation in typical office setups

To test the usefulness of personal ventilation (PV) (single round jet and a Coflow PV nozzle) in a typical office space, computational simulations of a four cubicle setup were conducted in a space with four optional PV systems in conjunction with displacement ventilation and compared with a setup with only displacement ventilation. The same total amount of fresh air entered the domain in all cases. Four sources were emitted into the space including a body, desk, wall and a floor source. Air quality in the breathing zone (BZ) of typical standing and seated heights throughout the space was compared with PV and without. It was found that PV improves air quality for a person seated in front of the system without drastically changing the air quality in locations where the space may be periodically occupied.
